 This movie is day one. This is the first day they invaded, and this movie focuses on a new character. Her name is Sam. Sam is terminally ill. Sam has a cat that she loves. She's not doing very well. I mean, she's not quite dead yet in Monty Python terms, but she's getting closer, and she decides to go into New York City with a friend of hers for a slice of pizza because, you know, if you're going to die, you may as well die happy.
